Given that a quantity \(Q(t)\) exhibiting exponential decay is described by the function $$ Q(t)=2000 e^{-0.06 \mathrm{~s}} $$ where \(t\) is measured in years, answer the following questions: a. What is the decay constant? b. What quantity is present initially? c. Complete the following table of values:
Express each equation in logarithmic form. $$2^{6}=64$$
The growth rate of Escherichia coli, a common bacterium found in the human intestine, is proportional to its size. Under ideal laboratory conditions, when this bacterium is grown in a nutrient broth medium, the number of cells in a culture doubles approximately every \(20 \mathrm{~min}\). a. If the initial cell population is 100 , determine the function \(Q(t)\) that expresses the exponential growth of the number of cells of this bacterium as a function of time \(t\) (in minutes). b. How long will it take for a colony of 100 cells to increase to a population of 1 million? \(\mathbf{c}\), If the initial cell population were 1000 , how would this alter our model?
Use logarithms to solve the equation for \(t\). $$4 e^{t-1}=4$$
Halley's law states that the barometric pressure (in inches of mercury) at an altitude of \(x \mathrm{mi}\) above sea level is approximated by the equation $$ p(x)=29.92 e^{-0.2 x} \quad(x \geq 0) $$ If the barometric pressure as measured by a hot-air balloonist is 20 in. of mercury, what is the balloonist's altitude?
